                  *"M-muh subjectivity means objective reality is whatever I want now watch me bless these crystals"*
                  Seriously though they'll start ditching string and other quantum theories once those theories start disagreeing actively with whatever magic woo-woo BS they're misusing them to support. Same with all cults. 'Evidence' is the fair-weather-friend of humans with BS to proport, to be dropped the moment someone with actual qualifications in the subject comes along.

I tried to explain it in most basic level and in an interesting way. I would like to have your opinion on my book ..

                                                                              They should be nearly straight, better chances of hitting particles than a curve like ray.

That's why radio waves can be heard just about anywhere except mountain ranges. Radio waves are so big just about the only thing that can block them are mountains. Another example is the frequency that is going to be used for 5G is higher energy than 4G which is why it can't travel as far as 4G can
